热导检测器对于气相色谱仪有着至关重要的作用。热导检测器是气相色谱仪的关键部件,主要用于气体成分和浓度的检测。
在气相色谱仪中,采用热导检测器检测物质成分的浓度变化,具有构造简单、测定范围广、稳定性好、线性范围宽等优点。
低压下，载气流经色谱柱及检测器的速度加快，峰扩展减弱，同时柱效和检测灵敏度提高．对低压色谱过程的传质系数和分离性能进行了探讨．

Thermal conductivity detectors play a crucial role in gas chromatographs. The thermal conductivity detector is a key component of a gas chromatograph, mainly used for detecting gas composition and concentration.
In gas chromatography, using a thermal conductivity detector to detect the concentration changes of substance components has the advantages of simple structure, wide measurement range, good stability, and wide linear range.
Under low pressure, the speed of carrier gas passing through the chromatographic column and detector increases, peak expansion weakens, and column efficiency and detection sensitivity increase. The mass transfer coefficient and separation performance of the low-pressure chromatographic process are discussed
